Hi Chris,
I added a separate test file (alternate-keywords.c) which includes
test cases for restrict, __restrict and __restrict__. I also included
some additional tests for other alternative keywords (hence the name
of the file), namely inline, typeof and their variants.
I have tested this only on 32-bit Linux so far. (I will do the other
platforms tomorrow, but I don't expect to find any problems) I wanted
to get this to you tonight.
ATB,
Ramsay Jones
